Image 1/1: One 3 mm Phillips screw.
  • Remove the following eight screws securing the lower case to the chassis:

    • One 3 mm Phillips screw.

    • Three 13.5 mm Phillips screws.

    • Four 3.5 mm Phillips screws.

On my model, it seemed the top-left was 3.5mm and the bottom 4 were 3 mm.

Make sure you have a good quality Phillips screwdriver. Mine had removable tips and had a small play at the connection. As a result I didn't have a good feel and damaged my screws (those securing the fan and the top left in step 23). Game over for me installing new thermal paste...

Be very carefull with your screws! Especially those on the inside.

  • Using the flat end of a spudger, pry the subwoofer connector straight up off the logic board.

Me, too, broke the subwoofer connector from the motherboard. I'd suggest removing the padding first so that you can see what kind of connector it is, then pry it loose (insert spudger where the cables enter the connector).

DO NOT REMOVE THE SUBWOOFER CONNECTION. Step 6 IS NOT NESCESSARY.

You can complete this guide without doing step 6 just BE CAREFUL as you already should be.

The subwoofer cable is NOT removable on some models, attempting to remove it, brakes it off the circuit board and them you are @@%#$$, like me. Thanks iFixit. Also it is not necessary to remove it to replace the optical drive.

This step is not necessary. Drive can be released without removing the screws.

I have a Macbook Pro 13, mid-2009, A1278 and the speaker broke it.

Can I put a speaker A1278 a macbook pro 13 mid-2012?

All speakers A1278 model work in any model of Macbook Pro A1278, regardless of the year?
